I purchased two Joy eGo mega atomizers and they gurgle? Very loud and annoying to the point that people turn around to look at where the noise is cumming from. They both did this right out of the package before I even put them on the battery or put a cart on them. Has anyone else had this issue ad if so were you able to stop it from gurgling. I love my eGo with these attys but don't like the attention I get when using them.
